Product Overview
The 133396-01 is a precision-engineered proximity probe extension cable from Bently Nevada, designed to serve as a critical link in machinery protection systems, connecting proximity probes to signal conditioners within Bently’s 3500, 3700, and 3300 Series monitoring ecosystems. Its core functionality is to transmit low-level analog signals—such as those from vibration, position, or speed sensors—over extended distances without degradation, ensuring that critical machinery health data reaches monitoring systems with accuracy and reliability.
As an essential component in industrial monitoring setups, the 133396-01 addresses the challenge of positioning sensors close to rotating equipment while locating signal processing hardware in safer, more accessible areas. What distinguishes it is its rugged construction, optimized to resist electromagnetic interference (EMI), radio-frequency interference (RFI), and harsh environmental conditions—common in power plants, refineries, and manufacturing facilities. Unlike generic cables, the 133396-01 is calibrated for seamless integration with Bently’s proximity probes and monitoring modules, eliminating signal loss and ensuring measurement consistency. This reliability makes it indispensable for maintaining the integrity of machinery health data, which is vital for early fault detection and preventing unplanned downtime.

Key Features and Benefits
The 133396-01 stands out for its dual-shielded design, combining foil and braided shielding with a drain wire to effectively block EMI and RFI—critical in industrial environments with high-voltage equipment, motors, or variable frequency drives. This shielding ensures that weak analog signals from proximity probes remain uncorrupted, preserving the accuracy of vibration, position, and speed measurements that are essential for detecting early machinery faults.
Its fluoropolymer insulation offers exceptional resistance to high temperatures, chemicals, and abrasion, making the 133396-01 suitable for harsh settings such as refineries, gas turbines, and chemical plants. This durability extends the cable’s lifespan, reducing the need for frequent replacements and lowering long-term maintenance costs.
The cable’s proprietary bayonet connectors provide a secure, vibration-resistant fit, preventing accidental disconnections that could interrupt monitoring. The 3-meter length offers flexibility in system design, allowing sensors to be placed optimally on machinery while keeping signal conditioners in protected, accessible locations. Additionally, the stranded 22 AWG conductors enhance flexibility, simplifying routing around equipment without compromising signal integrity.
Application Scenarios
The 133396-01 is widely deployed in industries where proximity probes are positioned several meters from monitoring systems, requiring reliable long-distance signal transmission. In natural gas power plants, it connects 3300 Series proximity probes on turbine shafts to 3500 monitoring racks located in control rooms, ensuring that critical vibration and axial position data remains accurate despite the EMI from generators and transformers.
In oil refineries, the 133396-01 links proximity probes on centrifugal compressor shafts to 3700 Series signal conditioners mounted in junction boxes, 3 meters away. Its chemical-resistant insulation withstands exposure to hydrocarbon vapors and cleaning solvents, maintaining signal integrity in harsh refinery environments.
In pulp and paper mills, the cable connects probes on dryer cylinder rolls to monitoring systems, routing through areas with high humidity and particulate matter. Its rugged construction prevents signal loss, ensuring that subtle changes in roll rotation—indicative of imbalance or bearing wear—are captured, avoiding costly production delays.

Installation and Maintenance
Installation of the 133396-01 requires careful handling to avoid damaging the shielding or connectors; ensure a minimum bend radius of 40mm to prevent conductor damage. The cable should be routed away from high-voltage lines, motors, or variable frequency drives to minimize EMI interference. Secure the cable with non-metallic clips to reduce vibration-induced wear, and ensure bayonet connectors are fully seated and locked to prevent signal loss. Verify compatibility with connected probes and monitoring modules before final installation.
For maintenance, inspect the 133396-01 quarterly for signs of insulation damage, shield fraying, or connector corrosion. Clean connectors with a dry, lint-free cloth to remove debris that could impede conductivity. Test signal integrity annually using the monitoring system’s diagnostic tools to confirm no degradation. Replace the cable every 8–10 years, or sooner if exposed to extreme conditions, to maintain reliable performance.
